In the study of Gigord and colleagues using Elderflower orchids, the allele frequencies of yellow and purple flowers varied such that when the yellow allele started to become rare, the reproductive success of purple flowers decreased and the reproductive success of yellow-flowered individuals increased in a process known as <u>frequency-dependent selection.</u>

Frequency-dependent selection is an evolutionary process in which the fitness of a phenotype or genotype is dependent on the frequency of that phenotype or genotype in a particular population.
- Positive frequency-dependent selection raises the fitness of a phenotype or genotype as it becomes more prevalent.
- In the case of negative frequency-dependent selection, the fitness of an increasingly prevalent phenotype or genotype diminishes.
In a broader sense, frequency-dependent selection involves biological interactions that make the fitness of an individual dependent on the frequencies of other genotypes or phenotypes within the population.

Answer:
The correct answer is option - microorganism.
Explanation:
The initial life form on earth was bacteria. These bacteria could live and survive in a toxic atmosphere at that time scale. Researchers and scientist believe that life in the earth were prokaryotes with no cell membrane and cell nucleus most probably bacteria.
All other organisms evolved later when there are enough oxygen and no toxicity in the environment.
Thus, the correct answer is option - microorganism.
By just calculating it's mass
